Mr. Colbert had a tepid start after his much-ballyhooed debut in September 2015. His show pulled ahead of Mr. Fallon’s in total viewers in February 2017 — the month after President Trump was inaugurated. Between then and the latest Nielsen report, Mr. Fallon had clung to the lead among the 18-to-49-year-old crowd. That gives him a slim lead over Mr. Fallon, who averaged 686,000 such viewers in that same period. Those figures have helped push Mr. Colbert to his first lead as measured by Nielsen rating points, with a margin of 0.54 to 0.53.
